Hey everybody. I'm Justin with AmericanMuscle.com, and this is my detailed review and Dyno test of the Bama X4/SF4 Power Flash Tuner loaded with two custom Bama tunes available for your 2015 and up V6 Mustang.
You should be checking out the Bama custom tuning options for your V6 if you're looking for a tune that's going to offer a big improvement in both performance and drivability. It's not going to break the bank and it's also going to provide some supports some other tuning options available here at AM will not.
Now let's first talk about the performance benefits, and then I'll get into some of the other benefits of running the custom Bama tune on your V6. Now we already established our baseline run earlier today using our automatic V6 here in the shop. We then uploaded our 93 octane Bama tune, re-ran the car, and here are the results.
Baseline run using our automatic V6 gave us 241 horsepower and 235 pound feet of torque at the rear wheels. With the 93 octane Bama performance tune uploaded, the car is now making 258 horsepower and 248 pound feet of torque. That's good for a peak gain of 17 horsepower over those baseline numbers, and gains of as much as 17 horsepower and 20 pound feet of torque under the curve.
All right guys, so as you can see the numbers are very impressive here using the Bama custom tuning, and you're picking up gains throughout the entire power bin. And I think that's the big point to make here. Usually you're seeing those big curve gains in one section of the graph or another. Here, you can see the lines are basically the equal distance apart throughout the entire RPM range, so that means that you're making that much more power throughout every RPM, and the car is just going to feel stronger overall.
Definitely a big thing to point out down low is that the car has this little dip in the factory line, but over the tube numbers, you can see that dip is no longer there. This is going to basically, going to feel like when you step on it, the car falls on its face a little bit, feels a little lazy. Not the case anymore, the second you step on it, it's going to take off like a rocket and overall the car's making big improvements.
Now on really cool thing to point out too is that using our Mustang dyno, we have the ability to simulate 0-60 time and quarter mile time. So baseline run, untuned with our automatic, the cars basically doing 0-60 in 6 seconds flat, and quarter mile time at 14 3 at 98. Now these numbers might differ from some of your favorite auto publications, or from track numbers, but these are accurate using the Mustang Dyno.
Now with the tune numbers the car dropped to a 5.2 0-60 time, that's almost a full second off, and the quarter mile time improved to a 13 7 at 99 miles an hour. Again that's a half a second improvement using those tune numbers. So, overall the tune, you can tell by the graph, it's doing its job, but those numbers definitely back it up as well.
Now that you know a little bit more about the Bama custom tuning, let's break down the tune itself. Now obviously those gains are pretty impressive, but let's talk about how the Bama team got to this point. Now it all starts with a development car and lots and lots of Dyno time. Now on the Dyno time, this is where the Bama team really starts playing with their cam timing, their ignition timing, torque tables, things like that along with some street refinements, and they were really able to nail a solid calibration that delivers a big bump in power without any other modifications.
Now these big power gains are nice, don't get me wrong, but as the old saying goes, "What does your Dyno sheet trap?" Well, as I already talked to you guys about, this is making for some big improvements at the track, knocking nearly a full second off your 0-60 time and just over a half a second off your quarter mile time. So obviously these are gains you're going to see at the drag strip, on the track, and even daily driving the car.
But the Bama tunes are more than just big power guys, they're also going to totally transform the drivability of your V6. They were able to do this by basically playing with that cam timing and achieving a much more useable RPM range and power band, unlocking a ton of torque down low. That's the stuff you're going to feel day in and day out, with some nice sizable gains up top as well. So essentially, totally transforming how your car feels.
Along with that improved drivability, I also notice the car's going to deliver a more improved, or more enjoyable, driving experience throughout. This means better throttle response overall, our automatic shift is firm, higher up in RPM range, it basically felt like a sportier car. And with all that said, you are getting the power, you are getting the drivability improvements, but you're still maintaining that factory reliability. So basically no stalling, no surging issues, the car's not going to give you any drama.
You are going to be receiving two custom tunes from Bama, a performance and race tune that are tailored specifically for you and your ride. Now, how does the Bama team do this? Well, they ask you a series of detailed questions about your V6 and all of its modifications before going to work creating your custom tunes.
Guys, I also want to point out that even though traditionally Bama is more of an entry level or value product when it comes to tuning here at Am, you are gong to be getting more for your money. For instance, Bama offers 85 and race gas tunes absolutely free of charge as long as you have the necessary fueling set up to run that 85, usually just a set of bigger injectors. In addition to that, you are getting free modifications or free tune revisions for life as needed, whether you're adding long tube headers, throttle bodies, things like that. Bama will be able to take acre of you at any point.
All right, now that you know a little more about the custom Bama tunes themselves, let's talk about how they're going to be transferred to your ride, and for that we have the Bama X4/SF4 power flash tuning device. The X4 is definitely one of the most commonly used tuning devices in the aftermarket and for good reason. It's very easy to use, has some nice features, and it's relatively affordable compared to some of your other options in the aftermarket.
Now beside carrying and uploading those custom tunes, I think you'll find that the X4 is capable of doing some nice things for you and your ride. Most notably the X4 is going to be used as a monitoring device, basically reading and displaying a bunch of useful information from your car's ECU at any time, all in real time.
Now you guys know the deal here, this is your fuel ration, your air intake temperature, ignition timing, RPM, things like that, and all of this information can easily be data logged at any point with a single button push. The X4 is also going to be used as your diagnostic tool, and what this means is you're going to be able to read and clear those diagnostic trouble codes, better known as check engine lights, at any point. And if you do wish to return your car to stock down the road, the X4 will be able to handle that for you.
Finally guys, this thing can take care of future firmware updates wirelessly, which is a nice little feature, and the X4 can hold up to 10 custom tunes at one time. All right, perhaps one of the best things about going with the custom tune besides the power gain is the ease of install. Hands down guys, one of the easiest modifications you'll ever do to your ride, and you won't even have to get your hands dirty.
Start off by locating your cars OBDII port. Now, on the S550, you're gong to find it on the lower left-hand portion of the dash. Plug the X4 tuner in and wait for it to power on. At that point, simply navigate to the tuning tab, select the custom tune you wish to upload, and from there on out basically follow the on-screen instructions, and you should be wrapped up in 30 minutes or less from start to finish. Again guys, very simple stuff here, so for that I'll give an easy one out of three wrenches on my overall difficulty meter.
Going with a custom after market tune is usually one of the big steps in pursuing bigger power goals for your V6. Now, having experienced the Bama custom tune V6 in the shop here, I can honestly say the car feels stronger now than it ever did before in stock form, and honestly feels more like a sports car. So, be sure to check out more of the Bama custom tuning options for your ride here at AmericanMuscle.com.

Questions & Answers (25)

5 Top Rated Questions

Will installing this tuner void any warranties?

The Bama X4/SF4 Power Flash Tuner is typically considered a warranty voiding item, and there have been several TSB's and GSB's from Ford in regard to aftermarket tunes.
That being said, the Magnuson–Moss Warranty Act provides you with protections with your rights in regards to your warranty. Additionally, the tuner can be used to return the vehicle to the stock tune, leaving no fingerprint in the PCM.

Hello! You should check with your local dealership, as every dealer handles modifications and tunes in warranty differently! Some are very accepting, some are very strict. So speak with your dealership and see what they say!

So will the purchase of this tuner eliminate the need to purchase one of the PedalMax Throttle Response mods? Basically will this do the same thing?

With the Bama X4/SF4 Power Flash Tuner w/ 2 Custom Tunes, Bama can enhance throttle response, and additionally aid your vehicle in producing more power. The Bama tuner will eliminate the need for the PedalMax throttle response, as it will perform the same functions, plus a little more!

So when I download the tune do you then loose the function of having drive mode and sport mode to choose from? Or is it possible the car run stock tune in drive and then if you put it in sport then the race tune kicks in? Thanks.

You will not loose your function of having the driver modes no. The Bama tuner will work together with the driver modes!

Power gains with the Bama X4/SF4 Power Flash Tuner will depend on the fuel octane used, and modifications done to the vehicle. It should be noted, E85 will require additional components, and fuel economy will be drastically reduced when using E85, as more is required compared to regular gasoline. More info on E85 tunes can be seen at the link below:
https://support.bamaperformance.com/hc/en-us/articles/201368909-Can-you-tune-for-E85-octane-

The Bama X4/SF4 Power Flash Tuner and other tuners will have minimal adjustment on the canned tunes. Unfortunately without knowing what is causing the surge, it is unclear what may be needing adjustment. We recommend speaking with SCT directly, or with one of our tuning specialists at BAMA to see if they can assist you with this.

Buckle in for a long review. I've had my Bama tunes for about 4 months now. Other mods are the BBK throttle body, Roush cold air intake and the Roush axle backs. I am going to break this down and hopefully give some of you V6 guys some insight before you pull the trigger.
Seat of your pants feel- First and foremost I have some pretty dang sticky Falken Tires and anytime PRIOR to the tune even with TC off it would not spin the tires from a dead stop when launching. I am pleased to say that on both performance and the race tune it spins from a dig and shifting from 1-2. Its definitely noticeable and you can tell it shifts much much firmer.
Bang for your buck- Overall I think its maybe a tad overpriced, yes it definitely adds HP and TQ, yes it changes the shift points/pressure but its not just the X4 you are paying for, you also getting the luxury of having FREE TUNES for life, so if you are planning on keeping the mustang for a while and have plans to mod it out, definitely buy this tuner so you can contact Bama for free revisions every time you put a new mod on.
Ease of use- American Muscle and Bama make the whole process streamline very well. AM sends the tuner and Bama will ask for you to fill out a list of mods done, after that it can take a day or 2 to receive the tunes (TUNING TAKES TIME) after you receive the tunes its plug and play! Takes roughly 7-10 Minutes and you're ready to go out and kill the streets!
Performance gain- I am not sure what the actual gain was since I did not dyne before or after, but you can find on AM the HP and TQ gain "claim." If you think this tuner will make you Fast like really fast you will be quickly disappointed. This isn't a supercharger, you are NOT going to see wicked gains. Maybe a Max of 25-35 HP/TQ
My only complaint is with SCT. First off THERE IS NO SCT software for Mac products so either you'll have to get windows on Mac or find someone to let you use their PC.
Thanks Guys I know it was a long review but I thought I would give my opinion based on my experience!

The Bama X4/SF4 Power Flash Tuner w/ 2 Custom Tunes (15-17 V6) is a really good tuner machine for your Mustang. The best part is that it came with 2 preloaded tune, I’m using the performance tune right now and you can feel the difference mostly within throttle response.

I was a bit skeptical since the only things I have done to this point are...K and N swap in air filter (not the CAI), and new mufflers. I was wrong. They could not send me the tuner with tunes on it already as they needed a code from the car ECU itself. After checking the update on the tuner, and plugging the tuner in and getting the code, I sent it to AM and got my 87 and 91 octane tunes very quickly (thanks Joel). I put in the 87 tune and the difference was immediate and substantial. The sound is a bit better, and the shifts are vastly improved (much more firm and at better rpms). The car stays in the power band more and it can be felt. Throttle response it also much better. I did notice that when the tranny was in drive mode, the downshift from 3rd to 2cd at about 25mph was a bit harsh. I emailed Joel and had a tweak on both tunes in less than an hour. Uploaded the new 87 and it works perfect. Would highly recommend this product.

I must say I am very happy with this purchase. The mods I have for my 15 Mustang V6 are just bolt on and this tuner really does bring out all the power and changes the feel of the S550. The Bama X4/SF4 is really easy to use and it’s not over detailed to intimidate you if you never had a hand held tuner, the tunes I got worked perfectly and only took 20 mins to install on the S550. The tuner has a lot of versatility to read code and clear codes even on other Fords. The tunes for life is what really sold me because I plan on adding more mods on the near future.

Horrible, bad investment. Throttle way to uncontrollable,sensative. Gas pedal wont even respond any thing past 30 or about 40 percent throttle it literally kills the pedal. It stops the brakes from working. Completely ruins the Ecu. Absolute trash, trash, trash, garbage. Ive had the tune 4 months now never used it onve and never ahing until i take ot back to the shop. Every thing else om the Website is great though:CAI, Throttle body, bbk headers, Custom circle tail lights and the full body light tints.

Bama has made it easy for v6 owners to wake up their beast. Just a simple map can wake up the engine, however if you want more power for your car specifically, you must datalog. This product is great and easy for tunes to be installed.

The tuner is good, its easy to install and everything. The only thing is, and I want to tell the people that are honestly looking into buying this is that the difference isn't like a "wow" experience, yeah you feel it, but its nothing dramatic that totally changes the way your car feels. Im sure that with supporting mods and a retune, youll get that wow feeling, but the tuner as a "raw" mod, meaning that its the only mod done to the car, its decent, not amazing, not bad.
